An expression is a phrase

avountae2003 · Answer

okay um it stands for a single number

vocaloid · Answer

both expressions and equations can contain variables and numbers

an expression doesn't have an equal sign, so you can't solve for the variable

ex. a + 4

an equation has an equal sign, so you can solve for the variable

ex. b + 2 = 4, b = 2
